Preheat your oven to 400°F (200°C) before you start cooking your sweet potatoes.
Wash and scrub your sweet potatoes under cold running water, and dry them with a clean towel.
Use a fork to poke holes all over your sweet potatoes. This allows steam to escape and prevents them from bursting while cooking.
Rub a light coating of oil (e.g., olive oil, coconut oil) all over your sweet potatoes. This helps to keep them moist and adds flavor.
Sprinkle salt and pepper over the sweet potatoes for added flavor.
Place your sweet potatoes on a baking sheet lined with parchment paper or aluminum foil.
Roast your sweet potatoes in the oven for about 45-50 minutes or until they are tender and easily pierced with a fork.
Let your sweet potatoes rest for a few minutes before serving. This allows them to cool slightly and lets the flavors settle.
Once cooked, you can add your favorite toppings such as butter, maple syrup, cinnamon, or chopped nuts.
Sweet potatoes make great leftovers and can be used in a variety of dishes, such as sweet potato fries, sweet potato casserole, and sweet potato pie.
